RDrive slowly and at an even speed through
the water.
R Do not stop and do not switch off the
engine.
! Do not open any of the vehicle's doors
while fording. Otherwise, water could get
into the vehicle interior and damage the
vehicle's electronics and interior
equipment.
R Water offers a high degree of resistance,
and the ground is slippery and in some
cases unstable. Therefore, it is difficult and
dangerous to pull away in the water.
R Ensure that a bow wave does not form as
you drive.
R Clean any mud from the tire tread after
fording.
R Apply the brakes to dry them after fording.
Winter driving
General notes
GWarning
If the vehicle becomes trapped in snow,
ensure that snow is kept away from the
exhaust pipe and from around the vehicle as
long as the engine is running. Otherwise,
poisonous carbon monoxide (CO) may enter
the vehicle, resulting in loss of consciousness
and even death.
To assure sufficient fresh air ventilation, open
a window slightly on the side of the vehicle
not facing the wind.
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center, at the onset of
winter.
Observe the notes in the "Winter operation"
section ( Y page 248).
Driving with summer tires
Observe the notes in the "Winter operation"
section ( Y page 248).
Slippery road surfaces
GWarning!
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
GWarning!
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle’s ABS will not prevent
this type of control loss.
Do not engage the transfer case in position
LOW when driving on ice or packed snow. At
speeds below 18 mph (30 km/h) vehicle
steering is adversely affected by the Off-road
ABS.
Drive particularly carefully on slippery road
surfaces. Avoid sudden acceleration, steering
and braking maneuvers. Do not use cruise
control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to position N.XTry to bring the vehicle under control using
corrective steering.
i For more information on driving with
snow chains, see ( Y page 248).
GWarning
Make sure that you do not endanger other
road users when you apply the brakes.

RCheck the depth of water before fording
rivers and streams.
R When fording, do not stop and do not
switch off the engine.
R Look out for obstacles such as rocks, holes,
tree stumps and furrows.
R Always keep the doors, rear door, windows
and the sliding sunroof closed while the
vehicle is in motion.
R Switch off cruise control.
R Do not stray from marked routes or paths.
R Adapt your speed to the terrain. The
rougher, steeper or more ruts on the
terrain, the slower your speed should be.
R Drive slowly and at an even speed through
the water. Ensure that a bow wave does not
form as you drive.
R On sand, drive quickly to overcome the
rolling resistance. Otherwise, the vehicle
could dig itself into the sand.
R Do not jump with the vehicle as this will
interrupt the vehicle's propulsion.
R Avoid high engine speeds. Drive at
reasonable engine speeds (maximum
3000 rpm).
R Do not shift the automatic transmission to
transmission position N.
R Always check the vehicle for damage after
off-road driving.
i Information about retrofitting special all-
terrain tires is available from any
authorized Mercedes-Benz Center.HEnvironmental note
Protection of the environment is of primary
importance. Treat nature with respect.
Observe all prohibiting signs.
Checklist before driving off-road
XEngine oil level: check the engine oil and
top it up if necessary.
Only then does the engine receive enough
oil when the vehicle is standing on a steep
incline.! If the engine oil warning lamp lights up
while the vehicle is in motion, stop the
vehicle in a safe place as soon as possible.
Check the engine oil level. The engine oil
warning lamp warning must not be ignored.
Continuing the journey while the symbol is
displayed could lead to engine damage.XWheel-changing tool kit: check that the
jack is working and make sure you have the
wheelbrace, a robust tow cable and a
folding spade in the vehicle.XWheels and tires: check the tire tread
depth and tire pressure.XCheck for damage and remove any foreign
objects, e.g. small stones, from the
wheels/tires.XReplace any missing valve caps.XReplace dented or damaged wheels.XCarry a sound spare wheel.
Checklist after driving off-road
GWarning
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possible
damage to your vehicle has occurred, you
should turn on the hazard warning flashers,
carefully slow down, and drive with caution to
an area which is a safe distance from the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle appears
unsafe, have the vehicle towed to the nearest
authorized Mercedes-Benz Center or tire
dealer for repairs.
Driving over rough terrain places greater
demands on your vehicle than driving on
normal roads. After driving off-road, check
the vehicle. This allows you to detect damage
promptly and reduce the risk of an accident
to yourself and other road users.
XShift the transfer case to HIGH
( Y page 126).XDisengage the differential locks
( Y page 129).Driving tips143Driving and parkingZProCarManuals.com
Page 146 of 288
XClean the headlamps and rear lights and
check for damage.XClean the front and rear license plates.XClean the wheels and tires with a water jet
and remove any foreign objects.XClean the wheels, tires, wheel arches and
the vehicle underside with a water jet;
check for any foreign objects and damage.XCheck whether twigs or other parts of
plants have become trapped. These
increase the risk of fire and can damage
fuel pipes, brake hoses or the rubber
bellows of the axle joints and propeller
shafts.XAfter the trip, examine without fail the
entire undercarriage, wheels, tires, brakes,
bodywork structure, steering, chassis and
exhaust system for damage.XAfter driving for extended periods across
sand, mud, gravel, water or in similarly dirty
conditions, have the brake discs, wheels,
brake pads/linings and axle joints checked
and cleaned.XIf you detect strong vibrations after off-road
driving, check for foreign objects in the
wheels and drivetrain and remove any that
you find. Foreign objects can disturb the
balance and cause vibrations.XTest the brakes.
Driving on sand
GWarning!
Do not reduce the tire inflation pressure
before driving through sand. However, if you
do so, remember to correct the tire inflation
pressure before continuing your trip. Driving
with reduced tire inflation pressure increases
the risk of losing control of the vehicle and
rolling over.
Observe the following rules when driving on
sand:
R shift the transfer case to
LOW (Y page 126).
R avoid high engine speeds.
R limit the shift range of the automatic
transmission according to the off-road
conditions.
R drive quickly to overcome the rolling
resistance. Otherwise, the vehicle could dig
itself into the sand.
R drive in the tracks of other vehicles if
possible. Make sure that the ruts are not
too deep, that the sand is firm enough and
that your vehicle has sufficient ground
clearance.
Tire ruts and gravel roads
Observe the following rules when driving
along ruts in off-road terrain or on roads with
loose gravel:
! Check that the ruts are not too deep and
that your vehicle has sufficient clearance.
Otherwise, your vehicle could be damaged
or bottom out and get stuck.
R shift the transfer case to
LOW (Y page 126).
R avoid high engine speeds.
R observe the safety notes (Y page 142) and
the general notes (Y page 142) on off-road
driving.
R restrict the shift range of the automatic
transmission to 1 (Y page 123).
R drive slowly.
R where ruts are too deep, drive with the
wheels of one side on the center grassy
area, if possible.

RAvoid high engine speeds – drive at
appropriate engine speeds (no more than
3000 rpm).
R Use the braking power of the engine when
driving down a slope. Observe the engine
speed, do not overrev the engine.
i Further information on the maximum
engine speed can be found in the
"Tachometer" and "Technical Data"
sections.
R Select a shift range appropriate to the
gradient.
R Before tackling steep downhill gradients,
select shift range 1 (Y page 123).
R Check the brakes after driving off-road for
a long time.GWarning!
Never turn the vehicle around on steep
inclines. The vehicle might roll over. If the
vehicle cannot complete the attempted climb,
back it down in reverse gear.
i Hill start assist will aid you when pulling
away on a hill.
For more information, see "Hill start assist"
( Y page 118).
Maximum gradient-climbing capability
Do not drive at an angle on slopes, inclines or
gradients, but instead follow the direct line of
fall. The maximum gradient-climbing
capability of your vehicle is 80%, which
corresponds to an approach/departure angle
of 38°. Note that the vehicle's gradient-
climbing capability depends on the off-road
conditions.
Accelerate carefully and make sure that the
wheels do not spin when driving on steep
terrain.
i If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS detects this and brakes the wheels
accordingly. The rear wheel torque is
increased, making it easier to drive off.
Brow of hill
When driving on an uphill gradient, reduce
pressure slightly on the accelerator
immediately before reaching the top of the hill
(do not shift the transmission to position N).
Use the vehicle's own impetus to drive over
the top of the hill.
This style of driving prevents:
R the vehicle from lifting off the ground on the
brow of a hill
R loss of traction
R the vehicle from traveling too quickly down
the other side
Driving downhill
R Before tackling steep downhill gradients,
select shift range 1 (Y page 123).
This way you use the engine's braking
effect to reduce the speed. If this is not
sufficient, brake gently. When doing so,
make sure that the vehicle is facing in the
direction of the line of fall.
R Observe the notes on driving in
mountainous terrain ( Y page 146).
R Drive slowly.
R Do not drive at an angle down steep
inclines. Steer into the line of fall and drive
with the front wheels aligned straight.
Otherwise, the vehicle could slip sideways,
tip and rollover.
R Check that the brakes are working normally
after a long downhill stretch.
i The special off-road ABS( Y page 56)
enables accurate, brief and repeated
locking of the front wheels, causing them
to dig into the loose ground. Note that when
the front wheels are fully braked, they slide
easily over the surface of the ground,
making it difficult to steer.

Range of the sensors
The sensors must be free of dirt, ice and
slush; otherwise they may not function
correctly. Clean the sensors regularly, taking
care not to scratch or damage them
